Definitions
- the invention relates to a hammer crusher, in particular for crushing old material, preferably metallic scrap, consisting of a housing with a material inlet and a material outlet covered with a classification grate, located in the region of a shaft, and a hammer rotor rotatably mounted in the housing.
- Hammer crushers of this type for example shown and described in DE-PS 1 272 091, are increasingly being used to shred car bodies, stoves, refrigerators, washing machines, steel furniture and the like. used.
- a dedusting system which is generally designed in two stages and explosion-proof and usually consists of a cyclone pre-separator and a wet scrubber, which are connected downstream of the hammer crusher.
- the size and suction performance of the dedusting system are unique determined solely by the high air output of the hammer rotor, which has so far not been accepted as being influenceable, and not by the output merely required for the amount of dust actually to be extracted. So far, this has led to the fact that the known dedusting systems not only have unnecessarily high energy consumption, but because of the oversizing, which is inevitably accepted, they are relatively expensive with, at the same time, relatively high noise pollution.
- the invention has for its object to provide a hammer crusher of the type mentioned, which makes it possible to assign or connect dedusting systems that are not oversized but can be dimensioned according to the requirements arising from the amount of dust.
- This object is achieved according to the invention on the basis of the basic idea of reducing the blower effect of the hammer rotor by dividing the shaft into at least two spaces one behind the other in the direction of rotation of the rotor.
- the "additional shaft" adjacent to the actual shaft is created, the surprising effect of which is air recirculation or continuous circulation, so that the blower effect of the hammer breaker is minimized and therefore the dedusting system, which is generally connected downstream, is less and on the actual dust accumulation can be dimensioned.
- a version with a horizontally mounted hammer rotor has proven particularly useful, in which the shaft is then located above the rotor and is covered with a preferably horizontal grading grate, which can also be curved.
- the additional shaft space provided according to the invention is then not delimited by the classification grate but surrounds the hammer rotor in a width adapted to the rotor power over a certain circumferential angle range; it preferably extends from the exit of the goods to the entry of the goods.
- the air connection to be provided between the two spaces is expediently achieved in the context of the invention by a baffle separating the spaces from one another, which extends at an angle to the grate plane from the edge of the grate facing the material inlet to close to the percussion circle of the rotor and in particular with openings or Breakthroughs are provided, which will be explained in detail.
- a hammer rotor 2 which can be driven in the direction of rotation R is mounted horizontally with its axis 3. It is equipped in a manner known per se with the rotor hammers, which are not particularly shown here, as actual crushing tools, which can be pivoted freely about their respective suspension on the circumference of the rotor 2 in radial planes.
- the dash-dotted circle 4 marks the so-called hammer impact circle 4 described by the outer edges of the rotor hammers.
- the housing 1 has a material inlet 5 for the material to be reprocessed, for example car bodies, which are introduced into the housing 1 via the slope 6 in a state that is usually already highly compressed.
- a classifying grate 7 which forms the product outlet is arranged above the hammer rotor 2 and still covers one through a discharge flap 8 for coarse parts which cannot be comminuted or only inadequately Baffle 9 to be explained in more detail and side walls (not designated in greater detail) formed a shaft 10 transversely to its axis.
- a hood 11 above the grating 7 serves to collect and deflect the shredded scrap passing through the grate and is provided with a connection 11a for a dedusting system, not shown. Through a laterally located, lower opening 12 of the hood 11, the processed goods fall onto or into suitable transport devices.
- the baffle 9 according to the invention is suspended or fastened directly below the classifying grate 7 in a slight inclined position in the housing 1 in such a way that it extends at an angle to the grate plane from the edge of the grate 7 facing the material inlet 5 to close to the impact circle 4.
- the baffle 9 has openings or openings 13 which are described in more detail below.
- the baffle 9 is slightly flared in the illustrated embodiment with its edge facing the rotor in the direction of the material inlet 5, the angle oC between the baffle surface 14 and a perpendicular to the plane of the grating 7 being chosen between approximately 10 0 and 30 ° can.
- a further anvil edge 16 is provided for further comminution, namely on the edge of the baffle 9 facing the rotor; in this area there is also one of the end fastenings 17 of the baffle 9.
- the openings or openings 13 passing through the baffle 9 should be dimensioned at least so that they also let through those pieces of scrap which are comminuted and / or compacted enough to pass through the grating 7.
- the air flow is influenced particularly favorably in the sense of the invention if larger dimensions are selected for the openings 13. If a rectangular cross-section is selected for the openings 13, then it is expedient to give the long sides of the cross-sectional rectangles a minimum length of approximately 80 mm to 100 mm, depending on the material processed.
- the sum of the inlet cross sections of the openings 13 should advantageously take up at least two thirds of the impact surface 14 of the baffle 9.
- the openings 13 continuously expand from the impact surface 14 of the baffle 9 to the rear thereof.
- Advantageous is in this case enclosed between two opposing panels 18, 19 of the openings 13 angle ⁇ in the range of 4 ° to 20 0, in particular between 6 ° and 16 ° chosen.
- the openings widening towards the outlet in this way prevent crushed parts from jamming in the openings.
- the impact wall 9 according to the invention in particular in connection with a housing wall 20 shaped approximately according to FIG a surprising, extremely beneficial effect.
- a substantial part of the amount of air conveyed by the fan action of the hammer rotor 2 into the shaft 10 below the classifying grate 7 is through the openings 13 in the baffle 9 in the direction of rotation R of the rotor 2 into the housing wall 20, which partly also extends from the arch to the material inlet 5 enclosed space 21 behind the baffle 9 and from there into the area of the inlet 5, supported by the slight negative pressure prevailing here relative to the space 21.
- the measures and features of the invention ensure that a substantial part of the air flow generated by the hammer rotor is conveyed in a circle through the baffle openings, namely initially into the space between the baffle and the inlet-side housing wall and from there again into the suction area of the hammer breaker at the material inlet. This reduces the amount of air sucked in from the outside and thus also the amount of air that has previously determined the dimensioning of the suction and blown off by the classifying grate.
